Referring norv to the drawings, im.-

proved hospital table includes a main table 10,'-Wliich may be'similar to af conventional i form of bedside table. The main table 10` includesa main supporting frame including corner posts 11, 12, 13 and 14, connected to gether adjacent their upper ends by tie mem-` bers`15, 16, 17 and 18 Whichin the present instance are tubular metalv members Welded adjacent their opposite ends to the adjacent corner posts. The corner posts are also'pref'- erably of tubularmetal construction and are provided with more Orless ornamental legl portions 19519 which may b'e lprovided `With casters 2.0, as shown in Fig. 1. The cornerV posts are also connected together .adjacent their Vlovver ends `by means of tie members sucli'as 21 and 22', as shown in Figs. 1 andl 4f.

The tie members'21 and 22 are alsopreier'ablyV *Y of tubular metal construction Vand Welded ad-Y jacentl their Y opposite ends to the adjacent corner posts.

*A table top fitting kover' the upper end of the mainframe is provided and includes7 inv this instance-,ametalplate 23 restingl onV the upper edgesof the frame members 15, 16, 17 and 18 and secured thereto by Suitable means such as Welding, as indicated at 24. A. removable' top member 25 having an ornamented edge portion 26- isv provided and adapted: to

be 'removably mounted on the plate 213', a 'layer of'deadening'material 2 7 being interposed 'be-j tween the plate 23 and top 25. Any suitabley means may be provided for'locking the removable top 25 in place. I'have shown the removable top provided Witha rebent flange portion 28.V extendinginwardly from one 'of' the ornamental edge portions 26- of the-top andfadaptedto interlock with'one or more suitable projections 29 on the tie member 15..

The vopposite vedge of the top memberr 2'5'Yis l notprovided Witha fla-nge such as28 so that' the v'top may be slipped' into place with the Harige-28 underneath the projections=29 until the opposite edge'BO Wi'lldropover the adje cent corner posts. The topmay then be locked in place by means ofa pair o screwsl and 32 as shown in Figs. 1 and 2Q The tie members `adjacent the lovverY ends ofithe cornerpostsmay be utilized Afor support# ing a shelf 33,` thelatter being/oi any suitable construction and? Secured in place in any con.

venient manner. It may be of the same construction as the table top above described, and

locked in place in a similar manner.

An auxiliary or table top member 34, mounted on the upper end of a vertically disposed post 35 is also supported by the main frame 10, and is adapted to be shifted from normal position overlying the main table top as shown in broken lines in Fig. 1, to offset position adjacent oneside of the main table top as shown in full lines in Fig. 1. When in the latter position, the shiftable top may conveniently be extended over a bed so that a person confined to the bed may conveniently use the table top.

The supporting post 35 includes inner and outer tubular metal members'V 36 and 37 rel spectively, the inner member being telescoped within the outer member and slidable longitudinally therein solas to `form an eXten-V lsible post. The post members 36 and 37 are square in the present instance so that they cannot rotate relative to each other, .but the same may be of any suitable cross section, it

o being only necessary to provide any desirable means for preventing such relative rotation.

vCircular cup-shaped bearing members 38 and 39 are secured to the post 37 for instance, by welding, at spaced points. Thebearing `members 38 and 39 are provided with laterally .outwardly extending iianges 40 and 41 respectively, which are adapted to be seatedV on the upper :edges of mounting brackets 42 and'43 as clearly shown inFig. 4; Closure f plates or caps 38a and 39a may be provided for Vclosing the upper ends of the cup-shaped bearing members 38 and 39 respectively. The mounting members 42 and 43 consist of metal straps bent to form a substantially circular .bearing portion, as clearly shown in Fig. 7

andattaching ears 44, whereby the members may be secured to cross members 46 and 47 which 'extend between `the corner posts 12 and 13 ofthe main supporting frame. The

" cross members l46 and 47 are attached adjacent their ends to the adjacent corner posts by screws as shown 'fat 45, or by other suitable means and are bowed outwardly a limited' amount as clearly shown'in Fig. 2. The bear-A fing members 42 and 43 may be secured to the cross members 46 and 47 intermediate their ends,-as shown in Fig. 2, by means of screws 48-48. 1

For locking. the post member 36 in the desired position of vertical adjustment relative to the post member 37 .the following described mechanism is provided. The post'member 37 isf slotted longitudinallyV intermediate lthe bearing members 38 and 3'9, as' shown at 49 Tand a member 50 having a plurality ofstops 51 formed therein is secured to the post member37 by means of .welding as shown at 52, withits stops 51 disposed opposite the slot 49 inthe post member. A dog 53 is pivotally4 mounted at 54 in a mounting bracket 55 within the lower end of the inner tubular member 36, the mounting member 55 being in the form of an inverted U member and secured in place in the lower end of the tubular member in any suitable manner. The dog 53 is provided with a tooth portion 56 which is adapted to engage the stops 51 and another tooth portion 57 which engages the inside face of the adj acent portion of the inner tubular member 36, (see Fig. 4). The inner tubular member 36 is slotted as shown at 58 to permit the tooth portion 56 of the dog to project outwardly into engagement with said stops 51. It will be notedthat theweight of the inner member 36 and the auxiliary top carried thereby normallytends to lower V.the member 36 in the outer member 37, and that the dog 53 is effective to prevent such lowering, the tooth 56 beingefective to engage .one of the stops 51, while the tooth 57 limits pivotal movement tion 56 of the dog outwardly so as to engage the stops 51. `It will be apparent that when the rod 59 is pulled upwardly, the dog 5,3 will be swung against the pressure of the spring 64l so asto clear the stops 51 and thereby to permit vertical adjustment o f the post membel f The auxiliary table top 34 includes a frame work 65 which in the present instance consists of tubular metal members joined at their ends to form a rectangular frame -of the desired dimensions, as clearlyLshownin Fig. 2. An intermediate tubular member 66 extends lengthwise of the top and is secured adjacent its outer end to the adjacent frame member by means of welding as shown at 67. The opposite end of the intermediate frame member 66 extends through the adjacent frame member as clearly shown in Figs. 2 and 4, and receives the shank portion 67 of va mounting bracket 68 as shown in Fig. 4. Screws 69-69 may be used for locking the shank 67 in place in the member 66 and the outer portion of the mount 68 is providedwith a socket part70', which-is adapted to lit over the upper end of the post member 36. The mounting bracket 68 may be locked on the post member 36 by means of screws as shown at 714471.

The table top 34 may be similar in construction to the main table top and includes a plate 72 which is welded to the frame 65, and a top member 73 which is removably mounted over Lesarss is adapted to lit under the adjacent portion of the frame 65 as shown in Fig. 2. .Screws such as shown at 77-77 extending through the downturned portion opposite the flange 7 6 and into the adjacent `frame portion, serveto lock the removable top in place. It will be understood that by removing therscrews 77 the adjacent edge of the removable top member 73V may be moved upwardly, clear of the adjacent edge of the `frame 65 after which A said main table top to offset position adjacent the top may be moved. laterally so as to free theflange 7 6 from the frame, after which the top may be. removed Vfor cleaning or other purposes, as desired.

The rod 59 projects through an aperture 78 in the mounting bracket 68 and a handle member 7 9 is secured to the bracket adjacent the upper end of the rod 59 so as to' facilitate lifting of the auxiliary table top and releasing of the dog 53. It will be understood that the .handle portion 7 9 may be gripped in such a way as to permit the bent end G3 of the rod 59 to be engaged by one finger, for instance, the index finger, so as to release the dog 53 and to permit raising or lowering of the auxiliary table top.

The lower end of the post member 37 is bent as shown in Fig. 1, to provide an offset foot portion 8O having a caster 81 secured thereto. The foot portion 8O is bent so as to project laterally .from the post in the direction in which the table member 34 projectsv from the post so that the foot will be effective to prevent tipping of the main frame l0, which might otherwise occur due to the weight of the auxiliary table top when the latter is in offset position as shown in Fig.`

1. It will be understood that the foot portion 8O turns with the post 35 and top 34, so

. that it is eifective in all positions of adjustment of the auxiliary table top to prevent the main frame 10 from tipping.
